Guys and Girls!
I have been driving myself nuts reading about sway sizes and what works best. I am driving mostly street. I will do a couple track days but not enough to worry about a huge bar. I have GF210's and 18x8.5 wheels with 235/40's for tires. I was in contact with a guy from flat iron's tuning by the name of Jon and here is what he had to say. It is a little technical but seems to make sense... He has sent me Whiteline 22mm adjustable fronts and 24 rear. I am trying to figure out if it should be the other way around like Clint reccomends and if so why? Thanks for the help in advance
So how does this apply to your car? Well, the stock bars on the STI are 20mm front and rear. On my WRX (which has the same chassis, and suspension geometry as an STI) I have 20mm front and 17mm sway-bars from the factory (and WRX's are notorious for under-steer). I first put on the 22mm rear sway-bar, and felt that the car was almost neutral, and at the limit, tended toward under-steer. I then put on the 22mm front bar and now I feel that the handling is a little more predictable because of the stiffer bars all around, but the car's balance has definitely shifted back toward under-steer. So when I get a change, I am going to shift my rear bar to its medium setting (24mm) to try to get back to neutral. This has been my experience so far...
